Doctor Thomas was born December, 1846, in Watertown, N. Y. His preliminary schooling was ended in the Philadelphia High school. In 1868 he graduated from the Philadelphia School of Pharmacy, but, deciding to abandon the drug business, entered the Homeopathic College of Medicine in Philadelphia and was graduated M. D. in 1871.
One year was spent as interne in the Albany City hospital, from which he came to Dayton. The death of Doctor Thomas, which came suddenly in 1890 in the vigor of manhood, resulted from burns due to an explosion of gasoline in a house in which he was making a professional call.
